Subject: [PATCH v2 06/13] drm/meson: Add support for HDMI venc modes and settings
This patch adds support for the supported HDMI Venc modes and add the VPP mux
value to switch to ENCP encoder.

* VENC Handle the pixels encoding to the output formats.
* We handle the following encodings :
* - CVBS Encoding via the ENCI encoder and VDAC digital to analog converter
- *
- * What is missing :
* - TMDS/HDMI Encoding via ENCI_DIV and ENCP
* - Setup of more clock rates for HDMI modes
+ *
+ * What is missing :
* - LCD Panel encoding via ENCL
* - TV Panel encoding via ENCT

+ *
+ * The ENCI is designed for PAl or NTSC encoding and can go through the VDAC
+ * directly for CVBS encoding or through the ENCI_DVI encoder for HDMI.
+ * The ENCP is designed for Progressive encoding but can also generate
+ * 1080i interlaced pixels, and was initialy desined to encode pixels for
+ * VDAC to output RGB ou YUV analog outputs.
+ * It's output is only used through the ENCP_DVI encoder for HDMI.
+ * The ENCL LVDS encoder is not implemented.
+ *
+ * The ENCI and ENCP encoders needs specially defined parameters for each
+ * supported mode and thus cannot be determined from standard video timings.
+ *
+ * The ENCI end ENCP DVI encoders are more generic and can generate any timings
+ * from the pixel data generated by ENCI or ENCP, so can use the standard video
+ * timings are source for HW parameters.
